We have a Genie S-60 Serial number 1829, 1997 year. We can start the gas engine and on turtle mode all works well with no issues, when we flip the switch to increase the throttle the engine dies. We had a repairman out and they replaced the ECM. Wat else might you suggest we investigate ?
Go to genies website and download the manual for your machine first. Usually has very easy step by step troubleshooting for these issues.
